Los productos derivados de sacarosa, como son los ésteres de sacarosa con ácidis grasos,han recibido creciente atención por su papel comol surfactantes conocirjos por ser no tóxicos y biodegradables. Estaparticularidad ha potenciado su empleo corno emulsificante en la industria alimentariariay farmacéuticp. farmacéutica. Por estas razones, la separaciónde ésteres de sacarosa es un desaflo permanente en las determinaciones anallticas. En este trabaio se presenta la separación de de sacarosa de sus mezclas con di y poliésieres en cromatografia en escala prepara(iva, empleando silice como adsorbente y una mezcla de acetato de etilo-metanol como solvente. La identificación de las fracciones correspondientes a los monoésteres fue realizada usando cromatografíen en placas placas delgadas delgadas con con la misma mezcla de solvente. Los resultados obtenidos muestran la potencialidad de Ia metodologia para ser.aplicada en la obtención de monoésteres puros imuestran
Sucrose derivatives, like esters of sucrose and fatty acids have received increasing attention for the irrmportant role as sudacfactants , wetl-known as non-ioxic and with an excellent biodegradability. These propeties have made their use as emulslfiers in food and pharmaceutical industries more important. That is why t\e separation of sucrose esters have a constant relevance in analytical determinations. In this paper, the separation oi sucrose monoesters from their mixtures with di and polyesters in a column liquid chromatography is presented, in the preparatory scale using silica as adsorbent and a mixture of methyl acetate and methanol as solvent.. The identification of the fractions corresponding to esters was done by thin layer chromatography , with the same mixture of so/vents. The results s/tow the posslbilities of this methodology in order to obtain pure monoesters.
